SwiftUI and Core Data - Pass Data between views the correct way

Hello everyone,

I am new to Core Data and I am trying to implement it on my app. I am concerned with memory leaking and I want to make sure that I am doing things the proper and safer way

At the moment I have two views. Putting it simply, I have one where I create the object and the other where I just display the attributes.

I have a var - that is the type of my Entity in Core Data and I declare it like this:

Code Block 
@State var observation: Observation?

Then inside my view when I press the button I have:

Code Block 
let newObservation = Observation(entity: Observation.entity(), insertInto: managedObjectContext)
newObservation.id = UUID()
newObservation.speciesName = finalLabel
...
do {
    try managedObjectContext.save()
    observation = newObservation
} catch {
    activeAlert = .canNotSaveCoreData
   showAlert.toggle()
}

I then send the observation object to my other view like this:

Code Block 
Details(sheetIsOpen: $sheetIsPresented, observation: observation!)

What intrigue me is the way I am sending the observation object. Is this correct / the standard way?

What should I be doing differently?

Thank you for your help!
